AI Technical Summary

Technical Problem

In the existing technology, the design of the three-dimensional spring sheet results in the spring sheet occupying too much space in the camera module, which limits the layout and performance improvement of the driving source components. In addition, the dispensing accuracy and stability during the assembly process are insufficient, which affects the AF function performance and module reliability.

Method used

The three-dimensional spring is integrally etched and formed by the spring body, AF spring wire and elastic baffle. The avoidance section of the AF main spring wire is designed to avoid the carrier glue groove. The AF and OIS functions are integrated by using a shared magnet drive mechanism, which reduces the number of magnets and assembly complexity.

Benefits of technology

It improves the accuracy and stability of AF and OIS performance, simplifies the assembly process, reduces the overall difficulty of the module, and enhances production efficiency and reliability.

Abstract

The invention discloses an elastic wire mechanism and an anti-shake lens. The filament bouncing mechanism comprises a three-dimensional elastic piece and an AF elastic piece. The AF elastic sheet comprises a carrier connecting part used for being connected with a carrier and a support connecting part used for being connected with a support. An AF main elastic wire used for resetting a carrier AF is arranged between the carrier connecting part and the support connecting part, and the AF main elastic wire comprises a functional section and a first avoiding section used for avoiding an AF dispensing groove in the carrier. The three-dimensional elastic sheet is integrally formed by etching the same base material of the elastic sheet body, the AF elastic wire and the elastic blocking sheet, a splicing link is avoided, the structural strength is high, the mechanical property is unified, and a carrier AF auxiliary reset function and a support OIS core reset function are integrated. And the AF main elastic wire is provided with a first avoiding section for pertinently avoiding a carrier AF dispensing groove, so that the normal operation of dispensing operation is ensured.
